Synthesis and characterization of molybdenum carbide doped with nickel

Molybdenum carbide doped with nanostructured nickel for application in degradation of reactive dyes

“…Structural characterization: carbide-like materials were produced, replicated and analyzed by X-ray diffraction (Fig. 1) using similar parameters employed in a previous study [16]. It was possible to identify the characteristic peaks of molybdenum carbide with orthorhombic structure (ICSD 18205) [2] on both Mo 2 C and Ni-doped Mo 2 C (5% and 10%) samples, featuring only Mo 2 C peaks.…”

“…The nickel nitrate reagent was weighed to the proportions of 5% and 10% by mass of atomic nickel. The reactants were mixed in a beaker with 42 mL of deionized water at 80 °C with magnetic stirring [16]. After mixing of the reactants and complete evaporation of water, the resulting mixture was dried in a muffle furnace at 70 °C for 7 h [17].…”

Hydrodeoxygenation of Furfural over Unsupported, SiO2‐supported or Metal‐promoted Mo Carbides: Tunning the Selectivity between 2‐Methylfuran and C10 Furoins Diesel Precursors

“…In another work, however, the α‐MoC formation was only observed for unsupported Mo carbides promoted with Ni, Pd, and Pt, which were able to promote the hydrogen and methane activation at lower temperatures during temperature‐programmed carburization compared to Cu and Co metals [57] . Nonetheless, several Ni‐promoted Mo carbides exhibited only the formation of β‐Mo 2 C phase [33,36,60–63] …”

“…[57] Nonetheless, several Ni-promoted Mo carbides exhibited only the formation of β-Mo 2 C phase. [33,36,[60][61][62][63] The diffractograms of the support and reference catalysts is shown in Figure 1b. The broad peak at 2θ = 21.9°corresponds to a classical pattern of amorphous SiO 2 (JCPDS 39-1425).…”
